Researchers found that apolipoprotein B and A-I were strongly linked to increased risk of fatal heart attack in both men and women. Higher concentrations of ApoA-I had a protective effect, suggesting apolipoproteins may be valuable for diagnosis and treatment.
A study found that nontechnical aspects of hospital care, such as emotional support and coordination of care, are crucial for heart attack patients' long-term health. Patients with worse hospital experiences reported poorer health at 12 months, but those with good follow-up care from outpatient providers showed similar health outcomes.
A UCSF study suggests that with effective programs, including anti-tobacco media campaigns and community-based efforts, the US can reduce its adult smoking rate from 23-26% to 15% by 2010. This goal is within reach due to successful large-scale tobacco control initiatives in states like California.
A US study of 2,481 heart disease patients found that treatment did not lower mortality rates despite reducing depression and boosting social support. Researchers hope to analyze data further to understand why the treatment failed to benefit patients.
A new Stanford University study analyzed the costs and benefits of two treatments: implantable cardioverter defibrillators (ICDs) and the drug amiodarone. ICDs were found to be the most effective in preventing sudden cardiac death, but also came with the highest costs. Amiodarone produced intermediate benefits and costs.
A new protein test has been developed to improve heart attack detection, particularly in cases of non-ST segment elevation heart attack. The test shows significant predictive value and could lead to a doubling of identified patients with mild heart attacks.
The study found that prehospital administration of the clot-dissolving drug reteplase decreased treatment time by more than 30 minutes at hospitals with average transport times and in-hospital treatment times. The savings exceeded 45 minutes at slower treatment time hospitals, highlighting the potential to improve patient outcomes.
Researchers found that troponin levels can accurately predict future heart attack risk, even when traditional measures are negative. The study suggests using troponin as a reliable indicator of cardiac cell damage, rather than creatine kinase-MB, to detect high-risk patients.

A new study found that hospital distress, particularly depression and anxiety, can predict poor heart attack outcomes and quality of life. Distressed patients reported more chest pain, poorer overall well-being, and increased healthcare usage.
Researchers at Duke University Medical Center found that almost 60% of patients with low-risk heart attacks do not experience complications beyond three days. While shorter stays may save resources, the study suggests that the additional day is often unnecessary and costs hundreds of millions of dollars annually.
Young women in Scotland are four times more likely to have a heart attack than those in the South of England, but survive at almost twice the rate. Ambulance response time may play a significant role in differences in mortality rates across UK regions.
The trial found that eptifibatide significantly reduced deaths and heart attacks by 40% within the first 48 hours of use. This represents a substantial improvement over the current standard treatment, abciximab, which costs $1,500 compared to $400 for eptifibatide.
Researchers found that aggressive treatment strategies, such as re-administration of clot-busters and emergency revascularization procedures, can reduce mortality rates almost threefold. However, many patients continue to receive conservative therapy despite these newer therapies being available.
A Boston study found that marijuana smoke increases the risk of a heart attack by nearly five-fold within the first hour, but the effect decreases rapidly over time. The study used a multicenter design and included 3,882 patients who survived heart attacks.
Middle-aged and elderly marijuana smokers increase their risk of a heart attack by more than four and a half times during the first hour after smoking, according to a recent study. The study found that the risk of a heart attack is highest in the first hour after use, but drops significantly after two hours.
Researchers at UCSD School of Medicine have discovered a defensive molecular mechanism launched by the body to protect against oxygen deprivation on the heart. HIF and VEGF, two angiogenesis genes, are activated in response to ischemia or infarction, attempting to increase decreasing blood flow.
A Yale study found that patients with mental illnesses are significantly less likely to undergo cardiovascular procedures, including angioplasty and coronary bypass surgery, compared to those without mental disorders. This disparity was not explained by the severity of cardiac illness or regional differences.
A new study reveals that tiny increases in creatine kinase-myocardial band (CK-MB) can indicate heart damage and predict increased risk of death. Elevated CK-MB levels are associated with higher rates of stroke, shock, and other complications.
A study found that spouses of heart attack patients share similar risk factors, including high body mass index and smoking habits. The researchers analyzed data from 170 couples and discovered that nearly 76% of couples were overweight or obese, with women being more likely to continue smoking after their partner's heart attack.
A six-year randomized study of 5,059 U.S. veterans found that taking one aspirin a day after a heart attack is as effective as combining it with an anti-clotting drug in reducing post-heart attack risk. The study recommends solo aspirin use due to its cost-effectiveness and lack of need for monitoring.
